DYNAMIC CONNECTION QUEUE DEPTH IN MULTI-SITE SYSTEMS

Aspects of the invention include techniques for implementing a dynamic queue depth in a multi-site system. A non-limiting example method includes initiating an initiator of a multi-site system and initiating a target system of the multi-site system. The target system includes a preferred site and a non-preferred site. The method includes receiving, by the target system, a session creation request from the initiator. The session creation request targets the non-preferred site. In response to the session creation request targeting the non-preferred site, a queue depth allocator of the multi-site system allocates a minimum queue depth to a path between the initiator and the non-preferred site.
